Description

Technical Field

[0001] This application relates to the field of freshwater fish farming, and in particular to a fish farming device that uses rainwater for self-cleaning. Background Technology

[0002] Chinese invention patent CN2024114959309 discloses a breeding device and method for improving the quality of grass carp. In this breeding device, large particulate matter, dirt and impurities in the water are removed through multiple filtration mechanisms such as physical filtration, brush filter box and biological filtration, thereby achieving sublimation filtration, stabilizing water quality and creating a healthy breeding environment.

[0003] However, the aforementioned aquaculture device has the following problems in application: 1. Currently, the device is placed outdoors for open-air use, and dust easily accumulates on the side walls and bottom, making it difficult to clean the inside of the device using only filtration. 2. The device requires external water pumps and other equipment that requires an external power source, making its use easily limited by the environment and not meeting the requirements of green aquaculture. Therefore, developing a fish farming device suitable for both indoor and outdoor use is an urgent problem for technical personnel to solve. Summary of the Invention

[0004] This invention provides a fish farming device that uses rainwater for self-cleaning. The device can utilize rainwater from outdoor rainy days to circulate and transport it into the farming pond to flush the inside of the pond, thereby achieving the function of self-cleaning inside the farming pond.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A rainwater-assisted self-cleaning fish farming device includes a farming pond, a circulating cleaning mechanism, and a rainwater self-sensing opening and closing mechanism.

[0007] The circulating cleaning mechanism includes a water pipe connected to the side end of the aquaculture pond; the rainwater self-sensing opening and closing mechanism includes a pressure cylinder, a water column, a water blocking component, a water pressure driving component, a spring, a locking ball, and a receiving block; the side end of the water column is provided with a groove adapted to the insertion of the locking ball, and the receiving block is provided with a receiving groove adapted to the movement path of the locking ball, and the receiving block is fixed on the pressure cylinder; the lower end of the pressure cylinder is provided with a sliding collar, which is slidably sleeved on the water column, and the inner end of the sliding collar is provided with an annular groove, one end of the spring is fixed to the upper end of the annular groove, and the other end is fixed to the side end of the water column; the pressure cylinder is slidably installed on the inner end of the water pipe.

[0008] The rainwater self-sensing opening and closing mechanism can collect rainwater with a certain water pressure and then recirculate it to the inside of the aquaculture pond through the water pipe to achieve the purpose of flushing the aquaculture pond. This prevents dust from accumulating on the bottom and side walls of the aquaculture pond when it is used outdoors, thus affecting the cleanliness of the fish farming environment.

[0009] Preferably, the water pressure drive assembly includes a return spring, a hollow insert, a drive pin, and an upper pressure plate; the hollow insert is slidably installed on the upper end of the water column, the upper pressure plate is fixed to the upper end of the insert, and the upper pressure plate is provided with a water passage hole; the drive pin is fixed to the upper pressure plate; one end of the return spring is fixed to the upper end of the water column, and the other end is fixed to the upper pressure plate; the side end of the insert is provided with a positioning groove for the insertion of a positioning ball.

[0010] The advantage of the water pressure drive component is that it only works under high water pressure, which meets the water pressure requirements inside the water pipe and thus flushes the aquaculture pond.

[0011] Preferably, the water-blocking assembly includes a water-blocking column, a positioning spring, a positioning ring, and a connecting block; the inner end of the water-passing column is provided with an inclined positioning ring, and correspondingly, the water-blocking column is provided with a clamping inclined surface that fits with the inclined positioning ring; the connecting block is fixed to the inner end of the water-passing column, and the connecting block is provided with a drain hole; the positioning ring is fixed to the upper end of the connecting block, and the lower end of the water-blocking column is provided with a positioning post, which slides through the hollow interior of the positioning ring; one end of the positioning spring is fixed to the water-blocking column, and the other end is fixed to the connecting block, and the positioning spring is sleeved on the outside of the positioning ring.

[0012] The water-blocking component serves to store water, thereby increasing the water pressure in the water pipe.

[0013] Preferably, the side end of the water-blocking column is provided with an annular groove, and a sealing rubber ring is provided inside the annular groove.

[0014] Preferably, the inner end of the sliding collar is provided with a limiting rib, and correspondingly, the side end of the water column is provided with a limiting groove that matches the limiting rib.

[0015] Preferably, a sealing plate is connected to the side end of the water column, and the sealing plate is fixed to the inner end of the water pipe.

[0016] Preferably, the circulating cleaning mechanism includes an annular flushing pipe, which is fixedly installed on the inner end of the aquaculture pond, and the aquaculture pond is connected to the water pipe.

[0017] Preferably, the aquaculture pond is connected to a drain pipe, and the drain pipe is connected to the water inlet pipe.

[0018] Preferably, the upper opening of the water pipe is provided with an isolation shield.

[0019] Compared with the prior art, the advantages or beneficial effects of the technical solution of this application include:

[0020] 1. In this application, by designing a circulating cleaning mechanism and a rainwater self-sensing opening and closing mechanism, rainwater is recycled to flush away dirt from the pool wall, thereby reducing manual maintenance.

[0021] 2. This fish farming device requires no external power supply and is driven entirely by rainwater pressure, reducing operating costs. It also meets green and environmentally friendly usage requirements, making it suitable for installation in front of courtyards and not limited by site conditions.

[0022] 3. Through the interlocking design of the water-blocking component and the water pressure drive, it is ensured that it will only start when the water pressure is sufficient, thus it can replace the water pump and has a stronger flushing force in the aquaculture pond.

[0031] The following detailed description of the embodiments of this application, in conjunction with the accompanying drawings, will provide a thorough understanding of how this application uses technical means to solve technical problems and achieve corresponding technical effects, enabling its implementation. The embodiments of this application and the various features within them can be combined with each other without conflict, and all resulting technical solutions are within the protection scope of this application.

[0032] It should be clearly stated that the embodiments described below are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0033] Example 1: This example provides a detailed description of the fish farming device.

[0034] A rainwater-assisted self-cleaning fish farming device includes a farming pond 20, a circulating cleaning mechanism, and a rainwater self-sensing opening and closing mechanism. The circulating cleaning mechanism includes a water pipe 22 connected to the side of the farming pond 20. The rainwater self-sensing opening and closing mechanism includes a pressure cylinder 1, a water column 12, a water blocking component, a water pressure drive component, a spring 8, a locking ball 7, and a receiving block 5. The side of the water column 12 is provided with a groove adapted to the insertion of the locking ball 7, and the receiving block 5 is provided with a receiving groove adapted to the movement path of the locking ball 7. The receiving block 5 is fixed on the pressure cylinder 1. The lower end of the pressure cylinder 1 is provided with a sliding collar, which is slidably fitted on the water column 12. The inner end of the sliding collar is provided with an annular groove 18. One end of the spring 8 is fixed to the upper end of the annular groove 18, and the other end is fixed to the side of the water column 12. The pressure cylinder 1 is slidably installed on the inner end of the water pipe 22.

[0035] The internal connection relationship and working principle of the rainwater self-sensing opening and closing mechanism are as follows:

[0036] like Figure 2 and Figure 3 As shown, the pressure-bearing cylinder 1 is slidably installed inside the water pipe 22. When rainwater enters the water pipe 22, the pressure-bearing cylinder 1 is impacted by the water pressure and moves downward, compressing the elastic spring 8. When the elastic spring 8 is compressed to its limit, the receiving groove on the receiving block 5 corresponds exactly to the locking ball 7. Similarly, when the water pressure drops, the pressure-bearing cylinder 1 will move upward, at which point the elastic spring 8 will return to its original position.

[0037] Example 2: Based on Example 1, this example provides a specific description of the water pressure drive assembly: The water pressure drive assembly includes a return spring 3, a hollow insert 6, a drive pin 4, and an upper pressure plate 2; the hollow insert 6 is slidably installed on the upper end of the water column 12, and the upper pressure plate 2 is fixed to the upper end of the insert 6, with a water passage hole provided on the upper pressure plate 2; the drive pin 4 is fixed on the upper pressure plate 2; one end of the return spring 3 is fixed to the upper end of the water column 12, and the other end is fixed to the upper pressure plate 2; the side end of the insert 6 is provided with a locking groove into which the fitting locking ball 7 is embedded.

[0038] The internal component connections and working principle of the water pressure drive assembly are as follows:

[0039] like Figure 3 and Figure 6 As shown, when the pressure-bearing cylinder 1 slides downward under water pressure, and water accumulates, the water pressure increases again, causing the upper pressure plate 2 to be impacted by the water pressure and drive the insert 6 to move downward along the water column. The drive pin 4, fixed to the upper pressure plate 2, will also move downward. At this time, as the insert 6 moves downward, it will push the locking ball 7 into the receiving groove on the receiving block 5.

[0040] Example 3: Based on Examples 1 and 2, this example provides a detailed description of the structure of the water-blocking component:

[0041] The water-blocking assembly includes a water-blocking column 11, a positioning spring 15, a positioning ring 14, and a connecting block 16. The inner end of the water-passing column 12 is provided with an inclined positioning ring, and correspondingly, the water-blocking column 11 is provided with a pressing inclined surface that fits into the inclined positioning ring. The connecting block 16 is fixed to the inner end of the water-passing column 12, and the connecting block 16 is provided with a drain hole 17. The positioning ring 14 is fixed to the upper end of the connecting block 16, and the lower end of the water-blocking column 11 is provided with a positioning post 13, which slides through the hollow interior of the positioning ring 14. One end of the positioning spring 15 is fixed to the water-blocking column 11, and the other end is fixed to the connecting block 16. The positioning spring 15 is sleeved on the outside of the positioning ring 14.

[0042] like Figure 3 and Figure 4 As shown, when the drive pin 4 moves downward, it pushes the water-blocking column 11 downward. At this time, the positioning spring 15 is compressed, and the abutting inclined surfaces on the inner ends of the water-blocking column 11 and the water-passing column 12 separate. Rainwater then flows from the water passage hole on the upper pressure plate 2 through the middle of the insert and into the gap between the water-blocking column 11 and the water-passing column 12, thus entering the water pipe 22. The diameter of the water pipe 22 should not be too large to avoid a decrease in water pressure after the rainwater flows out from the middle of the water-passing column 12, thus failing to achieve the flushing effect.

[0043] like Figure 3As shown, the side end of the water-blocking column 11 is provided with an annular groove, and a sealing rubber ring 10 is fitted inside the annular groove. The sealing rubber ring 10 mainly serves to prevent water leakage and facilitates water storage.

[0044] In this embodiment, a limiting rib 9 is provided on the inner end of the sliding collar, and correspondingly, a limiting groove adapted to the limiting rib 9 is provided on the side end of the water column 12. The cooperation between the limiting rib 9 and the limiting groove enables the sliding collar to slide up and down, preventing its circumferential movement.

[0045] In this embodiment, a sealing plate 26 is connected to the side end of the water column 12, and the sealing plate 26 and the inner end of the water pipe 22 are fixed.

[0046] like Figure 1 As shown, the circulating cleaning mechanism includes an annular flushing pipe 21, which is fixedly installed on the inner end of the aquaculture pond 20. The aquaculture pond 20 is connected to the water pipe 22.

[0047] like Figure 1 As shown, the aquaculture pond 20 is connected to a drain pipe 24, which is connected to a water inlet pipe 22. When the aquaculture pond 20 is full, the valve on the drain pipe 24 can be opened to allow water to flow into the water inlet pipe 22, thereby flushing the inner wall of the aquaculture pond 20.

[0048] like Figure 1 As shown, an isolation shield 25 is provided at the upper opening of the water pipe 22. The function of the isolation shield 25 is to prevent large stones or leaves from entering the water pipe 22.
